Though specimens have previously been confused with Rhododendron alabamense Rehder or its hybrids, phylogenetic relationships based on sequences of the nuclear gene RPB2-I gene showed R. colemanii to be a coherent species in a clade of section Pentanthera G. Don along with R. luteum Sweet and the Southeastern U.S. azaleas R. atlanticum (Ashe.

    Rhododendron is the largest genus in the family Ericaceae, with as many as 1, species, (though estimates vary from ) and is morphologically diverse. Consequently, the taxonomy has been historically complex.. Early history. Although Rhododendrons had been known since the description of Rhododendron hirsutum by Charles de l'Écluse (Clusius) in the sixteenth century, and were known to Clade: Tracheophytes. Rhododendron The Species / Classification. A genus as large and varied as Rhododendron becomes comprehensible only if its species are systematically arranged according to their affinity. The classification currently used in Britain was devised by Sir Isaac Bayley Balfour of the Royal Botanic Garden, Edinburgh, and further developed by other botanists there after his death in

The extensive collections of Rhododendron in the early 's from southern Asia made by Forrest, Rock, Kingdom-Ward, and others stimulated taxonomic work at Edinburgh Botanic Garden and Herbarium under the direction of Bayley Balfour.

Genetic relationships among specimens of the 15 currently recognized species in Rhododendron L. section Pentanthera G. Don were derived from sequence comparisons of the internal transcribed spacer (ITS) region. Sequences of the entire ITS region including ITS1, ITS2, and the S subunit were generated by direct sequencing of polymerase chain reaction (PCR) amplified by: Subgenus Hymenanthes (Blume) : Large leaf or elepidotes (without scales).

Section Brachycalyx Sweet comprises nearly 30 species in Rhododendron L. subg. Tsutsusi (Sweet) Pojark. (Ericaceae) and is mainly distributed from China to Japan as well as eastern Asia. A taxonomic revision of section Brachycalyx is proposed and eight species with one subspecies are recognized.

Most of these studies have aimed at higher-level relationships, despite the importance of lower ranks, such as sections, to most workers on the genus. Almost one-third of the species of Rhododendron are placed in one of the lepidote (scaly) sections, section Vireya (Blume) Cited by: 7.

Classification of Rhododendron species based on morphology has led to a consensus taxonomy recognizing the major subgenera Azaleastrum, Hymenanthes, Pentanthera, Rhododendron, Tsutsusi, and three minor ones.

Rhododendrons inhabit a wide range of environments (e.g., from humid tropical and subtropical forests to the alpine belt of mountains) and display striking morphological diversity (Cox and Cox, Cited by: 3.
